Animated Garfield needs no current warning symbol (3,4)
I believe the answer is:
red flag
This could be a double definition.
'animated garfield needs no current warning' is the first definition.
I know that 'warning' relates to this answer.
'symbol' is the second definition.
(I have seen 'Socialist symbol ' mean 'red flag' so perhaps 'symbol' could also mean 'red flag')
Can you help me to learn more?
(Other definitions for red flag that I've seen before include "Revolutionary symbol and song to the tune of Tannenbaum" , "Sign of trouble" , "Danger warning" , "signal to stop" , "Emblem of socialist revolution or danger" .)
